Bytnar JA, Lin J, Eaglehouse YL, et al. - Using data from the Department of Defense’s Automated Central Tumor Registry and the National Cancer Institute’s Surveillance, Epidemiology, and End Results 9 registries, researchers compared brain cancer incidence rates among active-duty military and general populations. They also compared rates between military service branches. Age- and gender-adjusted incidence rates of malignant neuroepithelial brain cancer in adults 20–54 years of age from 1990–2013 were computed and contrasted between the two populations. Per findings, the active-duty military population showed lower incidence rates of neuroepithelial brain cancer when compared with the US general population. In the active-duty population, the decreased incidence rate was seen in men, all races, persons 20–44 of age, and for all histological subtypes and time periods evaluated. Rates did not differ significantly between the military service branches.
